Cork oak (Quercus suber) is one of the rare trees with the ability to produce cork, a material widely used to make wine bottle stoppers, flooring and insulation materials, among many other uses. The molecular mechanisms of cork formation are still poorly understood, in great part due to the difficulty in studying a species with a long life-cycle and for which there is scarce molecular/genomic information. Cork oak forests are of great ecological importance and represent a major economic and social resource in Southern Europe and Northern Africa. However, global warming is threatening the cork oak forests by imposing thermal, hydric and many types of novel biotic stresses. Despite the economic and social value of the Q. suber species, few genomic resources have been developed, useful for biotechnological applications and improved forest management.

Autodesk, a company which develops design software, produced a synthetic Phi-X174 bacteriophage, a virus that infects E. coli bacteria but is totally benign for humans.
The effort was a sort of scientific homage to the work of the J. Craig Venter Institute, which first produced the self-replicating synthetic virus back in 2003, following a more than five-year research effort. In Autodesk’s case, it took a little more than two weeks and about $1,000.
That achievement says a lot about how far the science of synthetic biology has come — and a lot about where Autodesk is going.
A AutoDesk, criadora do software de modelação AutoCAD, criou o seu primeiro vírus. Mas não é um vírus informático, como à primeira vista possa parecer, mas sim biológico, já que a Autodesk também se lançou neste campo de pesquisa já lá vão dez anos. Este vírus é capaz de infectar a "clássica" bactéria-modelo E. coli.
